MK11 EVO / C370 COLOUR + R105 OCTO

This regulator set pairs the SCUBAPRO MK11 EVO first stage with the colour-frame C370 second stage and adds the R105 as an alternate air source. The MK11 EVO is a compact balanced diaphragm first stage in a forged brass body with metal thermal fins and a double spring layout, carrying two high pressure ports on a 15-degree angle and four high-flow low pressure ports. Intermediate pressure is externally adjustable, so a technician can set the system without opening it.

The C370 in this set uses an impact-resistant polymer front frame in place of the stainless steel one, supplied in graphite or white, and that frame can be swapped for any of the C370 colour frames sold separately. The second stage is air-balanced, with a diver-adjustable inhalation effort knob and a coaxial dive/pre-dive lever for VIVA. The R105 octopus is a classic downstream design with a metal valve housing and a reversible hose attachment on a 1 m high-visibility yellow Super-Flow hose.

First stage: MK11 EVO, balanced diaphragm, forged brass body, 4 low pressure and 2 high pressure ports, intermediate pressure 9.2 to 9.8 bar (133 to 142 psi), CE certified to EN 250A. Second stage: C370 with polymer colour frame in graphite or white, air-balanced. Octopus: R105 on a 1 m yellow Super-Flow hose. Connections: DIN 300 and INT 232.
